It helps to be self-sufficient and self-confident in order to make new friends and not get too lonely or homesick." If this sounds like you, it's important to consider whether you'll be able to return to the UK at the level you want, and in what ways the industry will have moved on in your absence, before making a decision. You might feel left behind by developments in your specialism or in the firm you previously worked for.
2 The second profile is older, someone with plenty of experience and who has perhaps has children who have left the family home. They're looking for a change of environment to finish off their career by doing something a bit different, reckons Flynn. "Working abroad is a chance to confront more extreme problems and develop yourself by tackling them. It can be a real plus point and add to people's employability back in the UK because you're increasing your knowledge base and experience of dealing with different situations. It can also make your final working years a lot more interesting."
This type of person might consider staying put in their new location after retiring.
